(5 Questions)
- Q1. Types of current,
- Ans.
There are two main types of current: direct current (DC) and alternating current (AC).
Direct current (DC) flows in one direction and has a constant magnitude.
Alternating current (AC) periodically changes direction and magnitude.
DC is commonly used in batteries and electronic devices.
AC is used in household electrical systems and power grids.
- Q2. What is electronic components
- Ans.
Electronic components are individual devices or parts that make up an electronic system or circuit.
Electronic components are used to control the flow of electric current within a circuit.
They can be passive components like resistors, capacitors, and inductors, which store or dissipate energy.
Active components like transistors, diodes, and integrated circuits amplify or control the current.
Examples of electronic compone...
- Q3. What is the use of solder,CRO MACHINE ETC..
- Ans.
Solder is used to join two metal pieces together while CRO machine is used to measure electrical signals.
Solder is a metal alloy that melts at a low temperature and is used to join two metal pieces together.
CRO machine (Cathode Ray Oscilloscope) is used to measure and display electrical signals in a waveform.
Other uses of solder include repairing electronic devices, plumbing, and jewelry making.
CRO machines are commonl...
- Q4. How can you solve any problem and hendel
- Ans.
I approach problems systematically, identify the root cause, and use my technical knowledge and experience to find a solution.
Analyze the problem and gather all relevant information
Identify the root cause of the problem
Use technical knowledge and experience to develop a solution
Test the solution to ensure it is effective
Communicate the solution to stakeholders
- Q5. Do you know about 1-phase ,3,phase how it's work and also about how AC-DC WORK?
- Ans.
1-phase and 3-phase are types of electrical power supply. AC-DC conversion involves changing the direction of current flow.
1-phase power supply has a single alternating current waveform, while 3-phase power supply has three alternating current waveforms that are 120 degrees out of phase with each other.
AC-DC conversion involves using a rectifier to change the direction of current flow from alternating to direct.

- Q1. What's transformer working and types?
- Ans.
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They are used to increase or decrease voltage levels in electrical circuits
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer
Step-up transformers increase voltage levels, while step-down...
- Q2. Resistor colour coding?
- Ans.
Resistor color coding uses colored bands to indicate resistance values and tolerances in electronic components.
Each resistor has 4-5 colored bands that represent numbers and tolerance.
The first two bands indicate significant digits; for example, red (2) and green (5) represent 25.
The third band is a multiplier; for instance, orange (3) means multiply by 1,000.
The fourth band indicates tolerance; gold means ±5%, silver ...
- Q3. Vcb working?
- Ans.
Vcb stands for Vacuum Circuit Breaker which is a type of electrical switch used for power distribution.
Vcb is used to interrupt or break the flow of electrical current in a circuit.
It uses vacuum as the arc quenching medium instead of air or oil.
Vcb is commonly used in high voltage applications such as power plants and substations.
It has several advantages over other types of circuit breakers such as low maintenance, h...
- Q4. Diode working?
- Ans.
A diode is an electronic component that allows current to flow in only one direction.
Diodes have two terminals: an anode and a cathode.
When a voltage is applied to the anode, current flows through the diode.
If the voltage is reversed, the diode blocks the current.
Diodes are commonly used in rectifiers, voltage regulators, and signal limiters.

3 Questions
- Q1. They asked me optimise the code I had written for the first question

- Ans.
The question is about finding the minimum steps to reach from a source string to a destination string using three operations.
BFS and DFS are graph traversal techniques that can be used to solve this problem.
BFS is typically used when finding the shortest path or exploring all possible paths in a graph.
DFS is useful when searching for a specific path or exploring deeply into a graph.
In this case, BFS can be used to find...
Interview Preparation Tips
Experience: • 1 question was on time complexity of searching an unsorted array.
• 2 questions were on recursion, ie, number of recursive calls.
• 1 question on analysing given function on string.
• 1 question was on probability(Two hotels, say A and B. Probability of moving from A to B is 2/3, staying at A is 1/3. Probability of moving from B to A and staying at B is 1/2. If they make decisions each hour, and if they were at A at 7:00 pm, what is the probability that they will be at B at 10:00 pm).
• If a set has elements {1,2,3,4 .... n}. Then what is the sum of elements of it's power set. (Ex: S = {1,2}. Then power set is {{},{1},{2},{1,2}}. The sum is 6.
• If a set has elements {1,2,3,4,5,6,7,8,9,10}. Then how many subsets of 3 elements has no consecutive elements.
• 1 question was on designing a DFA for a string starting with a and ending with c and has at least b in it.
• 1 question had machine instructions. We had to find out minimum number of cycles needed to execute the given set of instructions. (a) If the instructions are executed in the given order. (b) If the instructions are executed in random order.
• 1 puzzle on bridges.
Tips: In this round they not only see the answer. They also verify how you approached(So, give correct explanation to your answers).
Duration: 90 minutes
Total Questions: 10
Round: Coding Round
Experience: Two questions were there. 3 hours duration.
1. Long question, I don't remember fully. I'll just give input/output examples. It was basically on string decoding. If jon2snow3 is there the decoded string will be jonjonsnowjonjonsnowjonjonsnow. Given a string and an integer k we have print the kth character in the decoded string
input:
jon2snow3
8
output:
n
2. Given an array and an integer k return the number of contiguous sub arrays whose sum is divisible by k.
input format:
n k
input:
4 5
10 0 4 5
output:
4
explaination: {10},{0},{10,0},{5} are the sub arrays with sum divisible by 5.
Tips: You will have lots of time, so try to optimise the solution if you can. Remember here also they review each individual's code.
Round: Technical Interview
Experience: They will help you a lot if you are stuck at some point in the question. You have to be smart enough to grasp the clue.
Tips: They only ask questions only on data structures and algorithms.
Skill Tips: You have to be strong in coding. Algorithm questions will be mostly on dynamic programming. Data structures questions are mostly on trees.
Skills: C Programming, Maths(esp Probability), Algorithms And Data Structures
